HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 748,269, dated December1903- Applieat'ion filed November 22, 1902. Serial lllo. 13 2,380. (Nomodel.)

To all whom it may concern;

Be it known that I, LOUIS A. EGGERT, residing at Milwaukee, in thecounty of Milwaukee and State of Wisconsin, have invented a new anduseful Improvement in Hydrocarbon-Burners, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention relates to improvements in hydrocarbon-burners, and hasfor itsobject the production of a simple,' comparatively cheap, andeffective device by means of which a suitable combustible gaseous fluidmay be formed from the proper combination of a hydrocarbon gas andsteam.

A further object of this invention is to produce a simple combustiblegas-forming device adapted to be inserted and supported within the firepot or box of a furnace orstove or which by slight modification may beutilized for illuminating purposes.

These and other objects I attain by means of a device constructed asdescribed in the specification and illustrated in the drawings presentedherewith, in which- Figure 1 is a diagrammatic view, in dotted line andin section, of a furnace fire-pot within which a device embodying thisinvention is shown in side elevation. Fig. 2 is a side sectionalelevation of the device embodying this invention. I

Throughout both views like elements are denoted by like characters.

In the production of a device embodying this invention in the formillustrated in the drawings a gas-mixing chamber 3 is utilized, and thismixing-chamber may be formed of any suitable metal, such as iron, orfrom other fireproof material, such as clay, and the cham ber may be ofany desired form or shape, but will preferably have the shape of anopenbottomed cylinder tapered and narrowed into an upper neck, as shownin the drawings. The open bottom or mouth of this chamber will form theburner, and the flames formed from the ignited gas issuing from themouth will pass up around the mixing-chamber.

Located above the gas-mixing chamber is a steam-dome or steam-collectingchamber 4, and leading from a suitable source of Watersupply and coiledabout the gas-chamber is a pipe 5, which connects with thesteam-collecting chamber near its bottom, as at 6. The coil of pipesurrounding the gas-chamber forms a steam-generator, the steam fromwhich will rise into the steam-collecting chamber and from there willfeed into the upper neck portion of the gas-chamber through a suitablenozzle 7. The steam from the collecting-chamber, which passes throughnozzle 7 into the gas-chamber,is preferably taken from the upperportionof the collecting-chamber, Where the steam will be driest and hottest,by means of running the feed pipe nearly to the top of thesteam-chamber, as at 8. The Water-pipe 5 is provided with aregulating-valve 9, which is provided with an indicating device 10, bymeans of which the proper adjustment of the valve maybe quicklyaccomplished for supplying the water-pipe with the desired amount ofwater.

Leading from a suitable source of oil-supply, which oil will preferablybe a hydrocarbon oil, is a pipe 11, which enters the gaschamber,preferably at its top, through a nozzle 12. The oil-pipe at 11 isprovided witha valve l3,similar to valve 9,by means of which the flow ofoil to the chamber may be regulated. The steam and oil nozzles willpreferably be formed with a plurality of perforations, through which thesteam and oil will flow in the nature of a spray.

The device may be, supported within a fire box or pct 14 by any suitablemeans, and below the open end of the gas-chamber a collector 15, formedof asbestos or other suitable material or formed in the nature of'a pan,will be supported for collecting any of the oil which may drop from themixingchamber, and this may happen while the device is being started orwhile out of operation.

In operation water will be fed through the water-pipe and into thesteam-generator in proper quantity, so that there will always be asupply in the generator sufiicient to create a suitable steam-pressurein the steam-collecting chamber, and steam from the collecting-chamberin suitable quantity will feed to the upper portion of the gas-chamber.In starting the device, if desirable, a torch may be held or supportedbelow the same, so that steam will be generated before the valve in theoil-sup ply pipe is opened. This, however,

is not necessary. The valve in the oil-supply pipe will be regulated sothat the proper amount of oil will be fed from the oil-nozzle into thegas-chamber, and said oil will be commingled with the entering steam andcarried down to the mouth of the gas-chamber, where it will be ignited,and the flames from the burning fluid will pass up around thesteam-generator. In operation the walls of the gas-chamber will becomeheated, and as the oil enters the chamber it will be vaporized, and,together with the steam, will be forced out of the lower open end of thechamher.

It will be seen that the deviceis in a nature self governing orregulating after once put in operationthat is, the heat from thecombustion heats the walls of the gas-chamber, and thereby tends tovaporize the incoming oil, and heats the steam-generator whereby thesteam is generated and forced into the collecting-chainber,from which itissues in an even flow. The steam-collecting chamber being located abovethe generator and fire, where it will become intensely hot, tends tosuperheat the steam. A

It will be understood that the forms of the several elements in themake-up of this device may be varied without departing from the spiritof this invention.

What I claim as my invention is- 1. In a device of the characterdescribed, a mixing-chamber closed on all sides butits bottom and havingits bottom open to form a burner-mouth, a steam-generator surroundingsaid mixing-chamber and in the line of heat travel from saidburner-mouth, a steamcollecting chamber, a steam-passage from saidcollecting-chamber and said mixingchamber, and a pipe leading from asuitable source of oil-supply to said mixing-chamber. 2. In a device ofthe character described, a

' mixing-chamber closed on all sides but its hottom, a pipe leadingintosaid mixing-chamber at its upper end from asuitable'source of oilsupply,a steam-coil surrounding said mixingchamber and lying directly in thepath of heat, a steam-collecting chamber in the line of said heattravel, and a steam-passage from said collecting-chamber to the upperend of said mixing-chamber.

3. In a device of the character described, a

mixing-chamber closed on all sides but its bottom which forms aburner-mouth, a steamgenerator surrounding said mixing-chamber, asteam-collecting chamber located in the direct line of heat travel fromsaid burnermouth, and connecting with said generator, a steam-pipeleading from the upper portion of said collecting-chamber to saidmixing-chamber, an oil-supply pipe leading into said mixing-chamberadjacent to said steam-pipe and devices for regulating the supply ofwater to said generator and the supply of oil to said 4. In a device ofthe character described, a mixing-chamber having an open bottom form inga burner-mouth and having its other sides closed, a steam-collectingchamber located above said mixing-chamber in the path of travel of theheat from said burner, a steam pipe leading from the upper portion ofsaid collecting-chamber to the upper closed portion of saidmixing-chamber, asteam-coilsurrounding said mixing-chamber andconnecting with said collecting-chamber and an oilsupply pipe leadinginto the upper portion of said mixing-chamber adjacent to saidsteampipe.

5. In a device of the character described, a vertically disposedelongated gas mixing chamber having an open bottom forming aburner-mouth, a steam-collecting chamber located directly above saidmixing-chamber in line with the heat travel from said burnermouthwhereby the steam in said chamber is superheated, a steam-pipe leadingfrom said collecting-chamber into said mixing-chamber adjacent to itsupper end, a steam-coil surrounding said mixing-chamberand locatedin theline of heat travel from said burner-mouth and connected with saidsteam-collecting chamber, an oil-supply pipe leading into the upperport-ion of said mixing-chamber, spraynozzles for the oil and steampipes, a waterpipe leading to said generator and means for regulatingthe amounts of water and oil flowing to said device.

In testimony whereof Iaflix my signature in presence of two witnesses.
